摘要:

我们研究了在大规模道路网络中电动车(EVs)的能耗最优最短路径问题,其中下坡路段回收的能量引入了负的能量成本。虽然传统的点对点路径寻找算法为电动车假设已知的初始能量水平,但许多涉及可用能量不确定性的现实场景需要为所有可能的初始能量水平规划最优路径,这一任务被称为能耗最优路径搜索。现有解决方案通常依赖于标签修正框架内的专用路径合并过程,导致搜索复杂路径。在本文中,我们提出了一种基于多目标A*搜索的简单而有效的标签设置方法,该方法采用新颖的路径支配规则以避免生成和处理复杂路径。我们开发了四种变体方法,并在包含真实能耗数据的现实道路网络上进行了评估。实验结果表明,我们的能耗路径A*搜索在已知初始能量水平的情况下,性能与能耗最优A*相当。

英文摘要:

We study the energy-optimal shortest path problem for electric vehicles (EVs) in large-scale road networks, where recuperated energy along downhill segments introduces negative energy costs. While traditional point-to-point pathfinding algorithms for EVs assume a known initial energy level, many real-world scenarios involving uncertainty in available energy require planning optimal paths for all possible initial energy levels, a task known as energy-optimal profile search. Existing solutions typically rely on specialized profile-merging procedures within a label-correcting framework that results in searching over complex profiles. In this paper, we propose a simple yet effective label-setting approach based on multi-objective A* search, which employs a novel profile dominance rule to avoid generating and handling complex profiles. We develop four variants of our method and evaluate them on real-world road networks enriched with realistic energy consumption data. Experimental results demonstrate that our energy profile A* search achieves performance comparable to energy-optimal A* with a known initial energy level.
